Filed: 1989-06-02
Abstract: PURPOSE:To prevent leaning of the air-fuel ratio and an engine stall by controlling the decrease of fuel injection in the case of application of an outer load to an engine when the increase of fuel injection which is increased under specified operation conditions is decreased. CONSTITUTION:At the downstream of a surge tank 20 in an intake passage 16 of an engine 1, a fuel injection valve 21 is arranged. The fuel injection valve 21 is controlled by a control unit 26.

Abstract: PURPOSE:To obtain a soft X-rays multilayer film reflecting mirror, which is superior in endurance to a Li group/Ni multilayer film reflecting mirror and obtains a higher reflection factor than the multilayer film reflecting mirror of Be/Ni and SiO2/Ni. CONSTITUTION:LiF(lithium fluoride) is used as a material exhibiting higher refractive index among two materials forming a multilayer film, and since Ni(nickel) is used as a material exhibiting low refractive index, the refractive index of a LiF/Ni multilayer film composed of LiF and Ni is higher than those of the conventional SiO2/Ni multilayer film and Be/Ni multilayer film to soft X-rays of a wave length range of 23Angstrom -44Angstrom . In addition, since LiF is inactive and does not chemically react with moisture in the air, the film composed of LiF is chemically stable.
